All very generic, and will need to be modified for your particular type. Also, specifically relating to clean power-off stalls - will need to be modified for anything else.

First of all, teach the entry to the stall: HASELL checks, followed by idle power, using elevators to keep height, and possibly trimming until speed decays past Vy.

Once the student reaches this point, take control. Demonstrate the symptoms of the approaching stall - nose high, controls sloppy, slow airspeed, and, if you hold it a little longer, stall warner and light buffer. Demonstrate that, if you lower the nose just a tiny bit, all of these symptoms go away. Raise the nose again, and the symptoms return. Repeat a couple of times, then recover and let the student have a go.

When the student repeats the exercise, tell him to lower the nose enough that the symptoms go away, raise the nose so that they come back, etc, exactly as you've just demonstrated.

Then, take the controls, and demonstrate the recovery: lower the nose exactly the same amount as before, whilst simulatenously adding full power and controlling any yaw with rudder. Gradually raise the nose to the Vy attitude and climb away. After the demonstration, get the student to repeat the exercise.

Once the student has mastered the recover from the incipient stall, it's time to look at the full stall. Get the student to enter the stall, up to the incipient point, the same as before. Once the stall warner sounds, take the controls and demonstrate that, if you continue to try to maintain height without recovering, you enter the full stall. Point out the features of the full stall - heavy buffet, lowering of the nose, rate of descent, possible wing-drop.

Demonstrate that lowering the nose will stop all the symptoms of the full stall, just the same as it did for the incipient stall, but that you need to lower the nose a little more this time. Then demonstrate the full stall recovery, which is exactly the same as the incipient stall recovery but with more lowering of the nose necessary to stop the symptoms.

Finally, get the student to repeat the exercise.

All of this will, of course, be properly briefed prior to the flight.

You specifically ask about stalls with bank. Whether the stall was entered with bank, or whether the bank has occured due to wing-drop, the recovery is exactly the same as without bank, but once the symptoms of the stall have been removed (and not before) you can use aileron to level the wings.

Hope that helps,
